Her explanation is quite detailed, easy to read, and easy to follow; you can't go wrong if you follow her directions.
I do a couple of steps differently, mainly pinning from the back. I could never seem to get the pins on top where I could see them, once I was ready to attach the backing, and this was causing the pin heads to drag on the arm of the machine or on the ruler plate.
Once it’s pinned, I can roll it onto the take up bar to get to the end of the back and start pinning to the belly bar at the front of the machine.
Hope this makes sense!
